Front-end
#1

Olá pessoal, estou aqui mais uma vez, a bronca é a seguinte… simplismente nao consigo persistir no banco com os dados vindo da interface no caso a jsp.Quando rodo os teste unitários testando os meus DAOS ele persiste normal, Estou utilizando jsf hibernate/jpa e spring.

lá vai meu código e exceção.

#2

vc usou as bibliotecas que vieram no cd do livro ou pegou mais atualizadas? eu rodei esse exemplo e funcionou normal. pode ser alguma diferenca da versao das bibliotecas q vieram no cd que nao ta legal.

#3

eu nao usei as que estão no cd, pq estou utilizando o maven, mais eu peguei a mesma versão. Há mais eu acho que, nao é por esse motivo que não está funcionando, pq eu consigo persistir quando eu rodo os testes unitários

#4

e ae pessoal, alguem já passou por essa situaçao ???

#5

essa eh a categoriacontroller completa?

se eu nao me engano ta faltando a inicialicacao da categoria. veja como ta o getCategoria(); pq se ele ta retornando so categoria sem inicializar vai dar esse erro.

nao estou com o livro do edson goncalves aqui. mas eu lembro q no

public Categoria getCategoria() {
    return categoria;
}

esta como acima. ele inicializa a variavel em outro metodo.
tenta fazer assim:

public Categoria getCategoria() {
    if(categoria==null) {
        categoria = new Categoria();
    }
}

ae ele inicializa a variavel e vc vai conseguir setar os valores da tela no bean

#6

Eu conseguir identificar o erro, é o seguinte. Lá no meu applicationContext eu tenho um elemento

 <context:component-scan base-package="aqui faço o mapeamento dos meus controladores"/>

nele eu faço o mapeamento dos controladores que estão com anotações por exemplo: @Controller @Autowired e etcs.

faço o mapeamento do mesmo certinho ai vem o seguinte erro quando tento acessar minha página formCategoria.jsf, citada a cima.

o que pode ser isso pessoal ?

eu só nao consigo entender o seguinte… quando eu rodo minha classe de teste ela funciona normal, ele consegue injetar a dependencia


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml"})
public class TestCategoriaDao {

	private CategoriaDao categoriaDao;
	private Categoria categoria;

	@Autowired
	public void setCaegoriaDao(CategoriaDao categoriaDao) {
		this.categoriaDao = categoriaDao;
	}

	@Test
	public void testSalvar() {
		categoria = null;
		categoria = categoriaDao.salvar(getCategoria());
		assertNotNull(categoria);

		assertEquals("Teste", categoria.getCatNome());

	}

	@Test
	public void testAtualizar() {
		categoria = categoriaDao.pesquisarPorId(4);
		categoria.setCatNome("Teste 2");

		categoria = categoriaDao.atualizar(categoria);
		assertNotNull(categoria);
		assertEquals("Teste 2", categoria.getCatNome());

	}

	private Categoria getCategoria() {
		Categoria categoria = new Categoria();
		categoria.setCatNome("Teste");
		return categoria;
	}

	@Test
	public void testTodos() {
		List<Categoria> categorias = categoriaDao.todos();
		assertNotNull(categorias);
	}

	@Test
	public void testListPesqParam() {
		Map<String, Object> params = new HashMap<String, Object>();

		params.put("id", 4);
		List<Categoria> categorias = categoriaDao.listPesqParam(
				"SELECT p FROM Categoria p WHERE p.id=:id", params);
		assertNotNull(categorias);
		assertEquals(1, categorias.size());
		assertEquals("Teste 2", categorias.get(0).getCatNome());

	}

	@Test
	public void testPesqParam() {
		Map<String, Object> params = new HashMap<String, Object>();
		params.put("id", 4);
		Categoria categoria = categoriaDao.pesqParam(
				"SELECT p FROM Categoria p WHERE p.id=:id", params);
		assertNotNull(categoria);
		assertEquals("Teste 2", categoria.getCatNome());

	}

	@Ignore
	@Test
	public void testExcluir() {
		this.categoria = categoriaDao.pesquisarPorId(5);
		categoriaDao.excluir(categoria);
		Assert.assertNull(categoriaDao.pesquisarPorId(5));
	}

}
